Abstract
This invention is for LFP Design Page Wide XL 5000/8000 Blueprint which is a Page Wide XL SKU designed
for blueprint peak users. Typically blueprint plots are printed with cyan and magenta, but additionally
Page Wide includes black to allow blueprint customers print in black and white as well. The most intensive
blueprint users print in “digital blue” (cyan and magenta) and hardly ever in black and white. This very low
black usage could cause reliability problems in black ink channel.
For that case those users hardly ever use black to avoid reliability problems is very recommended
exercises black nozzles. The new idea is adding black dots in blueprints to increases black nozzles usage
preventing reliability issues. This new way to combine inks to print in blue, provide higher optical density
and increases nozzle robustness against reliability issues.
